Cannot run ASP 64-bit Web Form Application on Windows 7.

Exception has a place in this configuration also: MS Visual Studio 2010 Ultimate on Windows 7, MS Visual Studio 2012 on Windows 8.

The compiled 'dll' has to be exactly the 64-bit, because the database connection driver (IBM INFORMIX ODBC DRIVER 64-bit) throw exception: ERROR [IM014] [Microsoft][ODBC Driver Manager] The specified DSN contains an architecture mismatch between the Driver and Application.

In case 64-bit Windows Forms everything is working fine.

Could you possibly help me to solve this problem?

This is likely caused by the fact that only the 32-bit version of IIS Express is launched from Visual Studio. There is an unsupported registry key override in Visual Studio 2012 to force VS to launch the 64-bit version of IIS Express, details at http://visualstudio.uservoice.com/forums/121579-visual-studio/suggestions/3254745-allow-for-iis-express-64-bit-to-run-from-visual-st
